You'll get different responses from different users.  For some, one version works, the other doesn't........ its an enigma.

I can only speak of my experience, I dont have yet 7, so i cant complain about it.  However, there are enough posts on problems to think twice about a switch.

I too found 5 nearly unuseable, the interface was the main problem.   6 did not require this new "learning curve" and moved to a more user friendly format (IMHO).
